Efficient electroreduction of CO2 to C2 products over B-doped oxide-derived copper†
Abstract
B-Doped oxide-derived-Cu is a highly efficient electrocatalyst for transformation of CO2 to C2 products. The faradaic efficiency of C2 products could reach 48.2%, with a high current density of 33.4 mA cm−2 at low potentials in 0.1 M KHCO3 electrolyte. The excellent performance of the catalyst is mainly attributed to Cu+ species stabilized by the introduction of B.
